刚刚看到tweetstream的github上的构建失败了
sudo install g++
固定的
make:g++:未找到命令
阅读输出应该是你应该学会做的事情。尤其是当事情没有按计划进行时
取决于您对Linux的喜好。使用包管理器并安装gcc包
Arch-Linux:pacman-Syu-gcc
Ubuntu/Debian/Mint:apt-get-install-gcc
(您可能还需要安装build-essential
)
Fedora:yum安装gcc-c++
或yum-groupinstall“开发工具”
(适用于所有开发工具)
安装编译器后,重新运行gem安装,除非您缺少其他依赖项,否则应该没有问题您需要安装gcc。
运行此行:
sudo apt-get install build-essential
对于我来说(使用ubuntu)对于Amazon Linux:
sudo-yum安装gcc-c++
正如错误中所说,您缺少了g++
。搜索如何安装,你应该会很好。sudo安装g++,你是在生产Fedora 28,“开发工具”没有安装gcc-c++。我必须明确地安装那个软件包。然而,这对我起了作用。多谢!
